LASTING .MEOHANISH.

Patented Sept. 12, 1911.

Application filed March 19, 1910. Serial No. 850,434.

To all whom it may concern:

Be it known that I, MAT'IHIAS BRooK, a citizen of the United States,residing at Boston, in the county-of Sulfollcand State of Massachusetts,have invented certain Improvements in Lasting Mechanisms, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference characters on t1 several figures.

' This invention relates to machines for use in forming shoes andparticularly to heel lasting mechanism, and has for its object toprovide improved heel clamping means. i

One feature of this invention consists in providing improved means foractuating a into the shank of the last.

eelembracing band to cause it to clamp with equal pressure the oppositesides of the heel portions of shoes upon right and left.

lasts which are laterally unsymmetrical.

As iswell known,- many lasts in use at the present time are fuller atthe outer side of the heel portion, which corresponds with the outerside of the foot, than they are at the inner side of the heelflportion,particularly. at that part of the last which merges Any adjustment ofthe heel-bandrclosing mechanism which is arranged to cause it to closefarther on one side than on the other for one last is, (if course, wrongfor the other one of a pair of lasts. vention, therefore, means isprovided for equalizing thepressure of the'band-closing .mechan'i sm'atthe two sides of thelast. This means may advantageously be arranged toermit the band -closing mechanismto ad just the two end portions of theband relativel in accordance with the shape of the last efore the finalpressure for clamping faces These inclines cooperatewith abut-' men'tswhich cause the slide bars to move. inwardly and force the endjo'rtion's of the band against the sides of the as't assaid barsadvance.

Y In accordance with a preferred embodinient of'this inventioh theabutment-s at the in its closing e drawings indicating like parts in theIn accordance with the present intwo sides are connected for movementlaterally together to position the slide bars automatically as the bandcloses against the fuller side of the lastl In this positioning movementthe portion of the band first contacting with the fuller side of thelast pauses movement while the other end portion of t e band is forcedup into similar contact with the less full side of the last andthereafter the two end portions of the 'band are caused to clamp theshoe equally at the two sides of the heel. are shown as formed upon theop osite ends of a transverse bar which is gui ed by pins and slots andhas free movement transversely of the last.

The two abutments A movable connection is, employed be tween the ends ofthe band and the adjacent ends of the slide bars in orderto permit theslide bars to continue their advance movement for closing the endportions of the hand against the shoe after the advance movement of theband has been stopped by its engagement with the heel end of the last. Aconvenient form of movable connection for this purpose includes an anglelever fulcrumed on a slide bar and connected at. one end to the bandwhile its other end is con nected by a s ring to a fixed part of themachine. VVit'i this arrangement the end 'portion of the band is forcedinwardly by the turning of the angle lever. Thespring Frireturns theparts to normal position'wher.

the slide bars are retracted.

A novel feature of this mechanism consists inthe rovision of anadjustable angle lever forme to permit the lateral position of f e...end portion of the band with relation t4 the slide bars to be varied forshoes of diflierent sizes.

machine for the groups'of sizes comprised mcns, womens andchildrenssh-oes.- 13% the pgesent invention asingle an 1e 'leve, canadjusted to support the proper position for all the difl'etent' widthsof shoes. The construction employed prises an angle block, having theusual fularm 0 the lever and lm armfwluchis adjustable lengthwise insaid block for conpoint and the outer spring-engagednection with theband.

' and a transverse'shifting of t fixed portion of the machine head overwhich the, late 286 is movable and these pins stan in slots formed inthe arms of the plate near the lugs 285,- This arrangement of the lugson the movable plate 286 .permits lateral movement of the lugs togethere bars in company and effects an equalization of the inward pressure ofthe band 'at its two ends. This insures that the band shall clamp the'upper against the hollow inner side. of the .last with the same forceas it is clamped against the relatively full outer side of. the last.This equalization of the pressure at the two sides, in the regionof.'tl1e ends of. the heel stiifener, is of great importance in securinggood lasting, especially on such crooked and irregular lasts as many ofthose I wedgefaces of the relatively a now in use.

lhs advised, it is new by this invention to provide, for advancing andclosing of the ends of the heel or we band, a mechanism which includescooperating devices one of ,which, as the slide bars 192, has cam facesto effect closing'of the band ends and one of which, as the plate 286and its abutments 285, is mounted for self adjustment'transversely ofthe machine to equalize the band closing pressure at the two sldes ofthe shoe. M is -to be noted that the equalizer, which isthe plate 286,is independent in this embodiment of the invention from the means whichproduces the band. 7

In the use of the invention ashoe is properly supported vertically andthe last and the heel band are relatively actuated longitudinally andlaterally, -.during which movement the heel is thrust against the middleportion of the band and the ends of .the

band are closed snugly against thesides of the shoe. This latteractuation is" eflected by the forward movement of the crossheakl 190which moves longitudinally toward the right in Fig. 1 the bars 192 whichsupport the levers 194. which in turn support the frontendsof the band.The 006 era-ting vancing members 284 and 285, which are formedrespectively on the slide bars 192' and the equalizer 286, swing orturnthe slide bars 192 toward the center ofthemachine and 11love theband supporting levers 194 bodily inwardly toward-the shoe to clamfp theends of the hand against the sideso the shoe.

' If the shoe isless full on "one side at the end of the handthan on theother side the equalizer 286 moves freely ifrom thele'ss full side tothe larger side and thusprovides egual pressure onboth sides." The rearend o theband is supported by thestem 271 in r. the head of themachine"which constitutes theca'rrier upon which all thedescribed partsare movable Of course it is-iimmw terial whether the inclinedfaces 284are the advance moven'ient' of formed on the bars 192 or on the studs ofthe part 286 for the effect is't-he same in either case when these partsare relatively moved longitudinally of the shoe.

If it is desired to adjust the band for shoes of different widths thisis effected by manipulating the nuts 198, 198 .and screw 280 on thelevers 194 in an obvious way. If the band is to be removed the fingers274 are sprung downwardly against the springs ing screws if the screwshave been tightened, and the band can then be ,readily pulled out of itsholders. 1 When restored it is pressed close up against the under faceof the wipers.
